Wi-Fi-connected surveillance camera Dropcam can be useful for checking on your special furball when you're away from home. However, movement from an enthusiastic scratching post session registers the same as a burglar running off with your flatscreen, making it a less than ideal for security. That means you either have to deal with constant push notifications, or run the risk you're getting robbed. Today Dropcam announced that an update coming August will allow the cams to differentiate between people and pets. The company created an algorithm for picking out Fluffy without using depth sensors like other systems by analyzing hours of publicly-shared videos. That means she can keep on frolicking in that sun spot, and you don't have to hear about it all day.
